The lockdown may even be extended to more states as the total confirmed cases in the country reached 318 last night.
Governor Willie Obiano of Anambra State has, on his own, ordered that the state be shut down immediately.
Violators of the lockdown will be arrested, he said.
His Kano State counterpart, Dr. Abdullahi Ganduje, directed tricycle operators in the state to carry only one passenger for now following the detection of an infection in the state -a 75 year old man described as a retired ambassador.
